Here's my advice (which is contingent upon your actually selling a product or service): Setup an affiliate program and promote that as assiduously as you promote your actual product or service. Yes, doing so can take lots of work and managing it may take plenty of your time, but the trade-off can be well worth it. If you do things even 50% right you will end up with dozens, or even hundreds, of hungry internet marketers and webmasters promoting your product for you - at almost no cost to you. Pay your affiliates only after you get paid, (and after your merchant-account-mandated CC chargeback threshold passes). Flatter your top grossing affiliates with audio, video or email interviews (which you could publish to your startup's blog and which they will definitely spam the heck out of to everybody they know). Once you get enough traction and revenue to afford it, offload your affiliate management to a network like CJ or PepperJam. I used to be one of them so I can tell you, internet marketers are ALWAYS looking for a great product to sell/promote. Cut revenue-sharing deals with Internet Marketing forum owners for even more exposure. Do all that and, while I cannot guarantee that your product will succeed in the long run, I can guarantee that it won't fail as a result of nobody knowing it exists.
